There is a new group in town – that's ready to take the country over the cliff.

I am not talking about the Tea Party members of the House — the Michele Bachmanns, Steve Kings and Joe Wilsons, and 50 or so others who are members of the Tea Party Caucus. I am talking about the Senate, the greatest deliberative body.

Sens. Mike LeeMichael (Mike) Shumway LeeOvernight Defense: Senate sides with Trump on military role in Yemen | Dem vets push for new war authorization on Iraq anniversary | General says time isn't 'right' for space corps Senate sides with Trump on providing Saudi military support Senate, Trump clash over Saudi Arabia MORE (R-Utah), Rand PaulRandal (Rand) Howard PaulHouse poised to vote on .3T spending bill Overnight Finance: Lawmakers race to finalize omnibus | What we know about funding bill | White House on board | Fed raises rates for first time under Powell Senate passes controversial online sex trafficking bill MORE (R-Ky.), Ted CruzRafael (Ted) Edward CruzTrump can save Republicans and restore sanity to California in 2018 Cruz says Cambridge Analytica assured him its practices were legal Dem battling Cruz in Texas: ‘I can understand how people think this is crazy’ MORE (R-Texas) and Marco RubioMarco Antonio RubioRussia leak raises questions about staff undermining Trump House members urge Senate to confirm Trump's NASA nominee Rubio: McCabe 'should've been allowed to finish through the weekend' MORE (R-Fla.) seem intent on shutting down the government unless ObamaCare is defunded. They also don’t want the nation to pay its bills unless they get radical concessions on spending. In short, they are willing to continue to threaten to push the nation over the fiscal brink.

Obviously, Democrats are rolling their eyes, with a “here we go again” look. They remember the government shutdown of 1995, when then-Speaker Newt Gingrich got his head handed to him. They remember all the cost, political and financial, that occurred when Republicans refused to raise the debt ceiling in 2011. Obstruction and gridlock are not a useful strategy.

Emboldened with Congress’s 15 percent approval rating (pardon the sarcasm), the Republican “Cuckoo Caucus” is intent on standing in the doorway of progress on the economy.

The surprise over these last few days is how strong many Republican members have been in opposing the “Cuckoo Caucus” on both substantive and political grounds.

Sen. Richard BurrRichard Mauze BurrOvernight Cybersecurity: Zuckerberg breaks silence on Cambridge Analytica | Senators grill DHS chief on election security | Omnibus to include election cyber funds | Bill would create 'bug bounty' for State Omnibus to include election cybersecurity funds Overnight Cybersecurity: Senate Intel releases election security findings | Facebook to meet with officials on Capitol Hill amid Cambridge Analytica fallout | Orbitz admits possible breach MORE (R-N.C.) called Lee’s threat of blocking a continuing resolution that would keep the government open “the dumbest idea I’ve ever heard of.” 

Sen. Tom CoburnThomas (Tom) Allen CoburnPaul Ryan should realize that federal earmarks are the currency of cronyism Republicans in Congress shouldn't try to bring back earmarks Republicans should know reviving earmarks is a political nightmare MORE (R-Okla.) called efforts to defund ObamaCare in this manner “dishonest” and ‘hype.” A noted fiscal hawk, Coburn says he would “love to defund it ... but it will not work.”

Sen. Richard Shelby (R-Ala.) said it was “foolish” not to fund the government. Rep. Peter King (R-N.Y.) called it “terror politics.”Sen. John McCainJohn Sidney McCainZuckerberg: Maybe tech should face some regulations Schiff mocks Trump: Obama, Bush didn't need staff warning 'do not congratulate' Putin GOP senator tears into Trump for congratulating Putin MORE (R-Ariz.) referred to it as “shenanigans.”

Finally, Rep. Tom Cole (R-Okla.) said: “The only way Republicans will lose the House is to shut down the government or default on the debt ... it makes you look politically irresponsible.”

Could it be that we are beginning to see a small ray of sanity coming from Republicans in response to those who seem intent on taking down the economy through government gridlock and shutdown? Could it be that many conservatives are finally standing up to the extreme elements of the party? 

Color me naïve, but my sincere hope is that the “Cuckoo Caucus” will go the way of the dinosaurs and we can return to a Congress with something substantially higher approval rating.
