That's it. First Obama openly states in a joint press conference with Israeli PM, Netanyahu, longstanding US policy with regard to Israeli-Palestinian negotiations that final borders should be based on the 1967 borders with land swaps, leading to Netanyahu not only openly objecting to this strenuously, but to getting 28 standing ovations in Congress for complaining further about this to a mere 26 that Obama received for his State of the Union message; but now Obama flubbed a toast to the Queen of England, speaking over their national anthem as the orchestra began playing it in the middle of Obama's toast, an unforgivable blunder on the part of Obama, who clearly should have stopped in mid-sentence, as Rush Limbaugh explained in a 6 minutes and 42 seconds moment by moment explanation, clearly showing Obama's total unsuitability to serve as president ( http://www.mediate.com/online/limbaugh-rails-obama-on-toast-flub-im-tired-of-people-making-excuses-for-these-people ). Clearly, these actions by Obama are grounds for impeachment.
And, actually, it might be good to have those impeachment hearings going on those vitally important grounds, so that nobody will bother if Obama ignores the debt ceiling limit come August 2 and just orders US Treasury Secretary Geithner to just keep on issuing fresh US bonds to cover bills previously approved by the US Congress as they come due. Makes sense to me, :-).
