Who is "they" exactly? The party that spent the past 8 years talking about how deficits and spending are going to destroy the country are currently running things... and looking to increase deficits and spending. Self labeled "fiscal conservatives" just voted for a $1.5T unfunded tax cut, banking on essentially fairy dust (trickle down economic voodoo) to save the budget.
