Has anybody else noticed that basically every senator's approval rating is falling?

Senate Guru has a good illustration of SurveyUSA's recent approval ratings for 10 senators up for reelection in 2010.

Almost without exception, and without regard to party, all of them are headed downhill - from Sen. Charles GrassleyCharles (Chuck) Ernest GrassleyGrassley on Trump calling Putin: 'I wouldn't have a conversation with a criminal' Lawmakers zero in on Zuckerberg GOP senator blocking Trump's Intel nominee MORE's (R-Iowa) 12-point approval drop to Sen. Ron WydenRonald (Ron) Lee WydenOvernight Finance: Stocks bleed as Trump seeks new tariffs on China | House passes .3T omnibus | Senate delay could risk shutdown | All eyes on Rand Paul | Omnibus winners and losers Trump will delay steel tariffs for EU, others Overnight 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 MORE's (D-Ore.) six-point drop. Some are dropping faster than others, but each of them has lost approval points or gained disapproval points, and almost all have done both.

The numbers for Sen. Kirsten GillibrandKirsten Elizabeth GillibrandCynthia Nixon: Cuomo winning gold in Albany's 'corruption Olympics' 2020 Dems compete for top campaign operatives Amtrak to rename Rochester station after Louise Slaughter MORE (D-N.Y.) - 36 percent approval and 39 percent disapproval - mirror her drop in a Marist Poll released Monday.

Sen. Jim Bunning's (R-Kan.) approval has also dropped, according to other pollsters.

And appointed Sen. Michael BennetMichael Farrand Bennet2020 Dems unify around assault weapons ban, putting pressure on colleagues McConnell, Schumer tap colleagues to explore budget reform Democrats march toward single-payer health care MORE (R-Colo.) recently displayed some poor approval numbers of his own in a recent Public Policy Polling survey, despite the fact that many Colorado voters barely know him.

And this comes as Americans are supposedly starting to believe in Congress again?
