Two more new national polls confirming the rather dramatic tightening we've seen recently. First, Pew Research (April 23-27) shows Clinton gaining ground and Obama dropping a bit, turning a ten-point lead in March to just a two-point lead this month:

Obama 47 (-2 vs. last poll March 19-22)
Clinton 45 (+6)

CNN's new national survey (April 28-30) shows a different dynamic producing a similar result: Clinton hasn't gained at all, but Obama has lost a significant chunk of ground.

Overall, after reaching a high point of 10.4% on the day of the Pennsylvania primary nine days ago, Obama's lead over Clinton in the RCP National Average has plummeted to just 1.6%.

Here's a look at the RCP Average from April 1 through today:

In the general election match ups, Clinton and Obama both beat McCain by similar margins in both polls:

CNN: Obama 49 - McCain 45
Pew: Obama 50 - McCain 44

CNN: Clinton 49 - McCain 44
Pew: Clinton 49 - McCain 45

Overall, Clinton leads McCain by 3.1% in the RCP General Election Average, while Obama leads McCain by 0.9%.
