Sorry, electability is the number 1 factor to consider. I think my neighbor is right about nearly everything, but he's not electable and would therefore be a silly candidate. Like it or not, being a politician takes skill. Most people do not possess said skill. The public may say they want the "regular guy" to run, but those kind of candidates tend to get shredded and people end up laughing at them rather than voting for them. The more competitive the district the more skill one needs. West is getting good at being a politician, but he is nowhere near ready to run VP or President. For now, lets just make sure we help West win re-election to his congressional district and hope he will be ready for something bigger in the future.
Plato called politics “the highest art”. As you said it requires great skill not to mention incredible determination.
West is part of the GOP’s extremely deep bench which will become more evident with time. But he is clearly in no way ready for the top slots.
