GOP still favored for 2014
According to Politico, the Republicans are closing in on a senate majority, come 2014:
Republicans have more options. They’ve landed top recruits to take on first-term senators in New Hampshire and Colorado, nominated credible female candidates in open-seat contests in Michigan and Iowa, protected all of their incumbents from tea party challenges and thwarted more conservative candidates that could have hurt the GOP’s chances in states like North Carolina and Georgia.
With the general election field all but set, Republicans are looking to turn the midterms into a national referendum on Obama. Democrats want the focus to be squarely on the candidates, and they’re spending the typically quiet summer months trying to define Republican hopefuls as unlikeable and extreme.
