Never. There will be some single polls where he is slightly ahead, but he will never lead in the RCP-average.
Except he already lead in the RCP average.
I think MohamedChalid meant from here forward, until the election.
And remember trump only led the RCP Avg for 3 or 4 days, and it was only by a measly +0.2%.
It doesn't matter if your bank account is overdrawn by $1 or $800. It's still overdrawn. A lead is a lead.
OK. But would you rather have a positive balance in your bank account of say, $1
or $800, to help insure that you don't overdraw your account (lose the election) ?
And wouldn't it be better to have an $800 balance consistently and more often, rather than just relying on a "measly" $1 to "hold you above water" ?
