Arguments against direct democracy in the US:
-There is the added complexity of federalism, meaning significant differences between states, and also the issue of money.
-Even getting an initiative on the ballot takes time and money - so most ballot measures are therefore the product not so much of ordinary citizens but of interest groups.
-It takes money and organisation to collect the thousands of signatures often required to get an initiative on the ballot.
-Many groups employ professional petition consultants to collect signatures from eligible voters - for example, by going door to door or visiting a shopping mall.
-In 2020, the total raised on campaigning over direct democracy measures was close to $1.2 billion.
-Over $220 million was spent on a single California ballot initiative alone, to do with whether app-based taxi drivers, e.g. those who worked for Uber, should be classified as employees.
-It can lead to the 'tyranny of the majority', namely voters passing laws that negatively impact on a minority, e.g. requiring driving tests to only be in English.
-It can lead to inconsistencies and variations in laws between states, e.g. with same-sex marriage before the Obergefell verdict.
-It is often simply a political tactic used by 'sore losers', or those unhappy with specific policies. It also undermines representative government.
-Many would argue there are enough checks and balances already as governors have a veto. It simply adds another opportunity for stalemate and stalling over important issues. It can also limit the ability of state governments to do their job properly.
-It promotes 'democratic overload' and makes many ballots long and complicated, and so arguably depresses participation. Many would argue that pressure groups already have too much influence in US politics. It also adds to the overall cost of US elections.
-Turnout is often low, and parties often exploit direct democracy to influence the outcome of other elections. For instance, in 2018 in North Dakota, Democrats used an initiative on the legalisation of cannabis to attract young voters and liberals to vote for incumbent Democrat senator Heidi Heitkamp. On the other side, Republicans appealed to anti-immigrant instincts and introduced an initiative that would make it illegal for non-citizens to vote in North Dakota elections.
-Ordinary voters may not always fully understand complex laws. They may also vote for unsustainable measures such as cutting state taxes while increasing spending on public services, which can lead to huge budget deficits.
