McCaskill (D-Mo.) told “Meet the Press” moderator David Gregory that she believes the Republican House leader is in a difficult position as he works towards a deal with President Obama that he can sell to his caucus.

The Missouri senator said she feels “almost sorry for John Boehner, there is incredible pressure on him from a base of his party that is unreasonable about this and he’s got to decide: is his Speakership more important or is the country more important.”

McCaskill said Republicans were wedded to not raising taxes on even the wealthiest Americans, as the clock ticks down to January 1st, when automatic tax hikes and large spending cuts are set to take place if Washington fails to agree on an alternate deficit-reduction plan.
