Maginnis notes
that while polling data in Louisiana, from the Democrat-aligned firm Public
Policy Polling, conducted toward the end of that period showed by 47-32 percent
respondents were less likely to want to vote for GOP Senate candidate Rep. Bill Cassidy and gave incumbent Democrat
Sen. Mary Landrieu a 48-41 lead,
data from the Republican-oriented firm Harper Polling revealed
Landrieu led only 46-44 and 45 percent said they would vote for a Republican
for Senate while just 41 percent for a Democrat. This poll, however, was
conducted just before Oct. 1.
Interestingly, the PPP
numbers actually improved for Cassidy from the middle of August, when he
was supposedly down to Landrieu by 10 points and he gained a point in projected
vote. Further, the latest still showed Landrieu could not crack 50 percent
approval among voters; historically, incumbents who cannot do this a year from
an election almost always end up losing. And this was with Cassidy rated
unknown by 55 percent of voters and the 45 percent who ventured a likeability
rating on Cassidy about split; typically, as quality challengers become better
known, they gain proportionally more in liking than disliking among voters, to
the detriment of the incumbent’s vote share.
