Farage needs to delegate and find a group of say 4-5 very high profile starlets. Celebrity attracts votes, its the modern age, non-entities or tory colonel blimps will fail, as its still a FPP election.The 2022 GE will be very interesting - particularly for the more vocal Remain supporting MP's with small majorities in Brexit supporting seats. I suspect the main opposition party in those seats will put in opponents with strong Brexit credentials then flag the sitting MP's record in opposing Brexit. Given that floating voters in marginal seats don't have strong party loyalties, that could result in quite a few MP's being unseated.
The other joker in the pack could be Farage's new party, if they stand in 2022. If Brexit goes ahead on schedule, they might not win any seats, but if Farage is very selective in which seats he targets, he might split the vote of prominent Remain supporters ad change parliament to a more euro-skeptic composition.
Interesting times indeed.
