I'm not worried about him but that's just me. The reason why the polls are the way they are is because more voters are paying attention to the OH-SEN race, namely those who are Republicans.

The problem for the GOP is, Brown has led in the polls for much of the election cycle by 5+% points. Sure, polls may tighten or move in different directions, but if the GOP couldn't cut down on his lead for this amount of time, it suggests the following:

1) Brown still has clout and incumbency status in OH.

2) Moreno is really a flawed candidate who hasn't presented a credible enough campaign. Maybe he's getting more attention now but he's polling worse than Tim Sheehy in the MT-SEN race, which is saying a lot.
