looking forward to sing what he does in the next two years. >> i think now, particularly if obama gets a setback in the midterm, meaning his policies, republicans say take over congress, if that

little -- you'll feel a little bit of a cool breeze there. then on sunday, we'll see mostly cloudy skies, ahance of a shower in the afternoon. only a 30, maybe 40% chance. any rain on sunday will be light. and then the rai really comes in on monday with a high temperature of only 60 degrees. some areas will stay in the 50s all day long. and with the rainy day, it's not going toe very nice at all
