Bookies do have an idea about gamblers' habits...............
Yeah Biden will be ditched by the rats before the election...who they will roll out next in their desperation will be interesting...their candidates are chosen in a coke filled back room anyway...rat voters have no say in the process..hellary I reckon...
Bookies change the odds to keep the books even. Giving odds on Biden means they have too much money out on Trump. It’s simple math and has zero to do with popularity.
