Senate GOP botches 2012

Heading into the 2012 cycle, the Senate looked brutal for Democrats. The majority party had 23 seats up for grabs, compared to just 10 for Republicans. The GOP’s incumbents were mostly in safe territory, while Democrats had to defend a disproportionate number of seats in battleground or hostile territory. 

Thus, the question last year wasn’t whether Republicans would make gains, but whether Democrats would hold on to their six-seat majority. Nobody is asking that anymore.

Republicans had three apparent surefire pickups earlier this cycle — open Democratic seats in Nebraska and North Dakota, and the Missouri seat held by freshman Sen. Claire McCaskillClaire McCaskillGOP eyes big gamble on ObamaCare Oversight panel demands answers on Pentagon waste report Messer eyes challenging Donnelly for Indiana Senate seat MORE. Today, only Nebraska remains safely Republican. Missouri GOP nominee Rep. Todd Akin imploded with his “legitimate rape” comments, while North Dakota has remained stubbornly competitive thanks to former Democratic Attorney General Heidi HeitkampHeidi HeitkampMcConnell huddles with GOP rep to discuss possible ND Senate opening Senate Democrats dig in as shutdown approaches Overnight Finance: Senate Dems dig in as shutdown looms | Trump taps fast-food exec for Labor chief | Portland's new CEO tax MORE, who’s bucked her state’s red lean with effective retail politicking.

Top-tier GOP challengers in Florida, Hawaii, Michigan and New Mexico fizzled, while tens of millions of dollars in super-PAC attack ads did little to damage freshman Sen.

Free-spending conservative millionaires have made Connecticut and Pennsylvania surprisingly competitive, yet Democrats retain smallish but comfortable advantages in those states. In Wisconsin, Rep.

Thus, Democrats might lose as little as one seat, and at most four (Montana, Nebraska, North Dakota and Wisconsin). They’re also playing more offense than expected.

In addition to those sure pickups, Democrats have remained stubbornly competitive, thanks in large part to the Latino vote, in Arizona and Nevada. In Arizona, former Surgeon General Richard Carmona and Republican Rep. Jeff FlakeJeff FlakeReid bids farewell to the Senate Reid defends relationship with McConnell in farewell speech Graham, Durbin 'encouraged' by Trump's comments on Dreamers MORE have both hovered around 45 percent of the vote in the polling aggregate.

He won his race by 5.6 points. Obama outperformed the state’s aggregate polling by 6 points in 2008. If pollsters haven’t learned to better poll Nevada, Berkley might yet pull through.

Which leaves Indiana, where conservative primary voters exchanged longtime entrenched incumbent Sen. Dick Lugar for ideologue teabagger Richard Mourdock. The Republican has proven as crazy as Todd Akin, stating in a debate last week that a rape pregnancy was a gift from God. Yet another Republican’s bizarre beliefs about rape have made this a genuine Democratic pickup, despite Indiana’s red demographics.

Tally it up and the most likely outcome for Democrats is between losing two seats and gaining four, or between a 51-49 Democratic Senate (including independents) and a 57-43 one. In other words, the Senate GOP really botched 2012.
