Cantwell's lead over McGavick nearly gone: "Dwindling voter support for U.S. Sen. Maria Cantwell's re-election bid has put her in a statistical toss-up with her Republican opponent, according to a new poll announced Wednesday.
Rasmussen Reports, an independent national polling firm, said a survey of 500 likely Washington voters June 13 showed the Democratic incumbent leading challenger Mike McGavick 44 percent to 40 percent. The margin of error was plus or minus 4.5 percentage points."
So if the general picture is correct that politics has about a 20% penetration of the market. Then 50% of 20% is 10%.. so Senator Cnatwell's future is in the hands of 10% of eligible voters.
Politics is a tough business.
