Keep an eye on Delaware?

In addition to Pennsylvania and New York, things might be looking up for GOP fortunes in Delaware's 2010 Senate race. Rep. Mike Castle (R) leads possible Democratic opponent Beau Biden by over twenty points, according to one poll:

Poll respondents chose Castle by a margin of 21% with the incumbent congressman polling 55% to Biden’s 34%. Only 8% of respondents indicated that they are undecided. Among Republicans, Castle leads Biden by a margin of 82% to 12% and among Independents he leads Biden 55% to 28%. Biden leads among Democrats only by a 52% - 36% margin, however.
