Preposterous Meme: Obama taking on too much

I think this new G[reat]O[bstructionist]P[arty] meme that President Obama is taking on too much, has too much on his plate, isn't concentrating enough on the economic crisis, etc. is just preposterous. Were it not for these very obstructionists, I feel quite sure that the Obama administration could do a great deal more, and if anything I'm concerned that their efforts to date to cope with the myriad crises facing us are not enough, rather than too little.
