With just three weeks until election day, the battle for control of the U.S. Senate is in the homestretch.  Since the last forecast, the map has changed dramatically, with Democrats showing a bit of momentum.  As a reminder, Democrats currently maintain a slim 53–47 majority in the upper chamber.  Chances of a Republican takeover appear to be slipping away, however.

In the 2012 cycle, there are 33 Senate races on the ballot.  Twenty-three of those are currently held by Democrats; 10 are for open seats.  As things stand, there are eight races that can be considered truly competitive.

What follows is an updated analysis and forecast of each of those Senate races.  Although three weeks is an eternity in politics, this is an educated forecast based on current information as to the way the Senate map would look if the Presidential election were held today

The Result 

Since the last forecast, the race in Massachusetts has moved out of the “leans Republican” category and into “leans Democrat.”  In addition, Missouri has moved from “leans Republican” to “leans Democrat.”  Indiana has moved from the “toss-up” category to “leans Democrat,” and Virginia has moved out of the “toss-up” category to “leans Democrat.”  If the rest of the forecast holds true, Democrats would retain control of the U.S. Senate with an unchanged 53–47 majority.
