Larry Sabato, a longtime political analyst, has signed up with Politico as a columnist and his first piece predicts that the Republicans are lined up for a very good election year. Sabato, professor of politics and director of the University of Virginia Center for Politics, believes the GOP could win the Senate and take control of the entire Congress.
He assets that three factors are paramount in November: the president’s approval ratings, the strength of the economy,
and the election playing field. And those three
factors seem to be pointing toward Republican gains in both houses in
the 2014 midterms.

Here’s a part of his reasoning:

“The Democrats lost their weaker members in 2010 and failed to add
many seats in 2012; these disappointments protect them from drastic
House losses this coming November.

The Senate is a different story. There is no such thing as a typical
Senate election. These high-profile contests are idiosyncratic, driven
by distinctive circumstances, sometimes quirky candidates and massive
spending. A hidden determinant is the division of the Senate into three
classes—one-third is elected every two years, making the combination of
competitive Senate seats unpredictable and ever shifting, unlike in the
heavily gerrymandered House. One party is usually favored to gain seats
from the outset, thanks to the pattern of retirements as well as the
structure of the Senate class on the ballot.
