WPF Style Foreground of RadioButton not applied - wpf

Question

I have a style for my textblocks, and a style for my radio button.
When I add my radio buttons, they ignore the style for my foreground. The textblock style seems to have precedence and I can't get it the way I want it.
<Style TargetType="TextBlock" BasedOn="{StaticResource {x:Type TextBlock}}">
<Setter Property="FontFamily" Value="Daytona Light"/>
<Setter Property="FontSize" Value="22"/>
<Setter Property="HorizontalAlignment" Value="Left"/>
<Setter Property="VerticalAlignment" Value="Top"/>
<Setter Property="TextWrapping" Value="Wrap"/>
<Setter Property="Foreground" Value="White"/>
</Style>
<Style x:Key="Radio" TargetType="RadioButton" BasedOn="{StaticResource {x:Type ToggleButton}}">
<Setter Property="Foreground" Value="#1a3281"/>
<Setter Property="Background" Value="White"/>
<Setter Property="Template">
<Setter.Value>
<ControlTemplate TargetType="RadioButton">
<Border
Background="{TemplateBinding Background}">
<ContentPresenter HorizontalAlignment="Center" VerticalAlignment="Center" />
</Border>
<ControlTemplate.Triggers>
<Trigger Property="IsChecked" Value="True">
<Setter Property="Foreground" Value="White"/>
<Setter Property="Background" Value="#1a3281" />
</Trigger>
</ControlTemplate.Triggers>
</ControlTemplate>
</Setter.Value>
</Setter>
</Style>
I create my radio buttons in a stack panel
<StackPanel Grid.Column="1" Orientation="Horizontal">
<StackPanel.Resources>
<Style TargetType="RadioButton" BasedOn="{StaticResource Radio}">
<Setter Property="Margin" Value="50, 0, 0, 20"/>
<Setter Property="Width" Value="250"/>
<Setter Property="Height" Value="60"/>
<Setter Property="HorizontalAlignment" Value="Center"/>
<Setter Property="VerticalAlignment" Value="Center"/>
</Style>
</StackPanel.Resources>
<RadioButton GroupName="MainSelection" Command="{Binding ShowVideoCommand}" Content="Video">
</RadioButton>
<RadioButton GroupName="MainSelection" Command="{Binding ShowPresentationCommand}" Content="Presentation">
</RadioButton>
<RadioButton GroupName="MainSelection" Command="{Binding ShowSimulatorCommand}" Content="Simulator">
</RadioButton>
</StackPanel>
When I run my app, I see the radio buttons as full white rectangles. When the RadioButton is checked, the style for the background works fine (becomes blue, with text still white).
What am I doing wrong for my foreground style? Why is the textblock style always wins over my radio button style?
Even when I set Foreground="Red" in my RadioButton as follows
<RadioButton Foreground="Red" GroupName="MainSelection" Command="{Binding ShowVideoCommand}" Content="Video">
it won't show up. Text is always white.
