Are you saying Democrats will still control the Senate in 2015?
It will take more than GOP control of the senate to get a conviction. As it is, the majority of republicans in the senate would likely vote against impeachment.
Are you saying an impeachment conviction only requires a simple majority in the Senate?
If the Republicans win back the Senate in 2014, they still wouldn't have the 2/3rds necessary to convict Obama. IF we take the Senate we would end up with a slim majority and only nominal control. Even if Republicans had 3/4's of the Senate they wouldn't have the votes to convict Obama. Haven't you noticed he's black (well, half black) and even calling him out on his various failures draws endless calls of racism. Impeaching and convicting the first "black" President is just not going to happen. Even if Obama ate a live baby on national TV, I doubt he could be removed from office.
Limbaugh is right. Impeaching Obama is never going to happen.
