Heading into the final weekend of barnstorming before Election Day, there was a noticeable shift toward the GOP in many key House races while Democrats seem to be getting more good news than bad about the Senate map.
First, the Senate math:
Yes, it’s quite possible (even likely) that Democrats such as Sens. Sherrod Brown (Ohio) and Bob Casey (Pa.) will have closer margins on Election Day than most expect. But Democrats are likely to hold both seats, and the climb for Republicans to net the four seats they need for an outright majority (if President Barack Obama is re-elected) seems steep heading into election week.
Here’s what we know: Republicans are likely to pick up two Senate seats in Nebraska and North Dakota (although the race there remains close). Those gains are likely to be offset by Democratic pickups in Massachusetts and Maine, where an Independent is poised to win and will likely caucus with Democrats. Assuming Republicans hold their seats in Arizona and Nevada, which seems like a good bet, that’s a zero net gain, leaving the chamber’s makeup at 53 Democrats and 47 Republicans. Full story
