Democratic parties adopting right wing policies will not benefit from them. The people will vote for the original.

Right wing parties also don't have any real policies that are going to help the part of the population that is voting for them. So it makes no sense objectively to implement this.

Democratic parties will lose their values and gain nothing in terms of votes.

The so-called democratic parties are trying to do that. They're now in favor of:

• More border security so Frontex can drown even more migrants in the Mediterranean.
• Detaining the ones who make it over in concentration camps.
• Making it easier to deport people.
• Criminalizing Muslims for supporting Palestine.

These "democrats" are doing all this hate-speech, Hetze, and blatant violations of human rights. They took these policies directly from the far-right, and now pretend to fucking oppose the AfD? Fucking hypocritical assholes.

It won't work either, because none of that has anything to do with people's economic prospects, which is the real reason most of them are angry. So they're still going to be angry with whoever is in power, no matter how many foreigners they deport and murder and scapegoat.

While yes, that is part of the solution, there are also people that simply think that way. They think they are better, that they deserve X, and thus vote that way. Unless you fundamentally change their mind or promise then what they want, you will not get their vote.
