The chances Republicans have of retaking control of the Senate this November are beginning to waver, with seats the GOP thought it would win seemingly slipping away from its grasp. However, the GOP has been boosted, as previously secure Democratic states have started to lean toward them.

Opinion polls for Republicans in Virginia, Massachusetts and Wisconsin were disappointing, but were partially offset by GOP gains in the state of Connecticut where its chances of winning a seat had all but been written off previously.

Maine is expected to be won by Angus King, the state’s former governor, who is an independent and likely will caucus with Democrats. In Massachusetts, Elizabeth Warren, a Democrat, currently leads Sen. Scott Brown a Republican. In order for the GOP to take back control of the Senate, it needs to net six seats the Democrats currently hold.

Even in Indiana, the current race is not a sure thing for the GOP, following the defeat in the primary of Senator Dick Lugar by Richard Mourdock who has been backed by the tea party. Indiana’s last poll, taken over two months ago, had Mourdock holding only a 2% lead over Joe Donnelly the Democrat.

The RealClearPolitics website now predicts that the Democrats will win 48 seats in the Senate, the Republicans 45 and seven remain too close to predict. Those too close include Indiana, Connecticut, Massachusetts, North Dakota, Montana, Wisconsin and Virginia.

A senior Republican spokesperson said the Party has stepped back in certain states, but moved forward in others.
