Dick Burr's got all that money. But sometimes buckets of money can seem like exactly what they are ... proof that a politician is bought & paid for.
Another concern for Burr is that incumbents who earn less than 50% of the vote at this stage of a campaign are considered politically vulnerable, and no incumbent has been reelected to the seat [Burr] holds since 1968. The incumbent may benefit, however, from the fact that the political environment is very difficult for Democrats this year.
That last point is a pretty blunt instrument, Mr. Pollster, when the actual "political environment" might more accurately said to be "very difficult" for incumbents. Most of whom are Democrats, granted. But not in the case of North Carolina's senior senator.
