Senate Minority Leader Mitch McConnell (R-Ky.), above, will face a primary challenger from the right wing of the GOP before the 2014 general election. McConnell will compete against Matt Bevin, a businessman with support from the tea party, in the May 20 Kentucky Republican Senate primary, the most high-profile challenge to the party's establishment of the year. McConnell held a strong lead over Bevin in recent polling. If McConnell wins, he will face Kentucky Secretary of State Alison Lundergan Grimes in the general election. Grimes is neck and neck with McConnell in the latest polls. Democrats are particularly set on defeating McConnell, who has been a key leader in Republican opposition to President Obama's agenda.
