For the Senate, it’s not numerically possible...however a strong enough showing might get a few Dems who will play ball if only to save themselves in 2016.
I note that when leadership changes. you also get a few folks jumping party lines. While that can mean liberals are deluding Conservatism, it can also mean that some Democrats are sick and of their own party too.
I would love to see the Democrat Party destroyed, but it would simply mean the Leftists would congregate under a different flag.
Thanks again for the post Lepton. I appreciate you mentioning the numerical possibilities or lack thereof.
